Hooks like "post-checkout" require that hooks have a different working
directory than the initial process. Pipe that directly through to struct
child_process.
Because we can just run 'git -C <some-dir> hook run ...' it shouldn't be
necessary to pipe this option through the frontend. In fact, this
reduces the possibility of users running hooks which affect some part of
the filesystem outside of the repo in question.

Needed later for "post-checkout" conversion.
